Grinding mechanism of diamond micro powder

The diamond micro powder grinding process can be seen as a micro cutting of the workpiece by free abrasive through grinding tools, which has complex physical and chemical comprehensive effects. Its main functions are as follows:
1. Diamond micro powder cutting effect. Because the material of the grinding tool is softer than that of the workpiece being ground, the abrasive particles in the abrasive are embedded into the surface of the grinding tool or float, forming the bottom of the blade. Next, micro cut the surface of the workpiece.
2. Chemical reaction of diamond micro powder. When using chromium oxide, stearic acid or other abrasives, a very thin oxide film will form on the surface of the workpiece. The oxide film layer is prone to wear and rapidly oxidizes continuously during the grinding process. After forming, it will continuously wear and tear, thereby accelerating the grinding process and reducing surface roughness.
3. Plastic deformation of diamond micro powder, passivation of abrasive particles on the surface of the workpiece, deformation of the processed material, ironing of peaks and valleys on the surface of the workpiece during plastic deformation or hardening of the workpiece during repeated deformation, ultimately resulting in a micro shrinking night. When grinding, the following requirements should be met: the surface shape accuracy of the grinding tool should be high, the workpiece should perform complex composite movements, and the grinding agent must be suitable.

How to choose diamond coated cutting tools

Like any other cutting tool, the lifespan of stone carving knives varies, mainly depending on the material being cut, the selected feed rate and cutting speed, as well as the geometric shape of the workpiece. Generally speaking, the lifespan of diamond coated tools for processing graphite is 10-20 times that of uncoated hard alloy tools, and in some cases may even be longer. In this way, almost any machining task can be completed with a single tool without the need for tool replacement due to tool wear, avoiding machining interruptions and recalibration, making it possible to achieve unmanned machining. In the processing of composite materials, it is also entirely possible to achieve a longer tool life

Do you know the raw materials for high-quality cutting blades?

Glass cutting blades are particularly suitable for accurate cutting and slotting of optical and electronic components due to the strong holding ability and high wear resistance of diamond abrasive particles by binders.

How to choose between using CBN grinding wheel or diamond grinding wheel?

CBN and diamond belong to the category of super abrasives, and are called super abrasives because their hardness is much higher than other traditional abrasives. So, both are super abrasives, how do you distinguish between the two, and how do you choose the grinding wheel abrasives that are suitable for your own production? Firstly, we need to understand the characteristics of both.

Development status of diamond micro powder industry: The industry is developing towards intelligent production

Diamond micro powder refers to diamond particles with a particle size smaller than 54 microns and a chemical composition of carbon, which is the hardest substance in nature. Diamond micro powder is a micron or submicron level ultrafine diamond powder formed by processing diamond single crystals through crushing, ball milling, and other processes. Diamond has high strength and good wear resistance, with a Mohs hardness of 10 and a microhardness of 10000kg/mm2. Its microhardness is 1000 times higher than that of quartz and 150 times higher than that of corundum. Therefore, diamond micro powder, as a superhard abrasive, has unparalleled grinding ability compared to other products and is increasingly receiving high attention from developed industrial countries.

Semiconductor Industry's Expectations for High Quality Diamond

Semiconductor materials are a type of functional material with conductivity between conductive and insulating materials at room temperature. Its conductivity will significantly change with temperature, light exposure, and doping, especially doping can change the conductivity and type of semiconductor, which is the basic basis for its wide application in manufacturing various electronic components and integrated circuits.

The company is positioned to focus on the production, research and development, and innovation of diamond micropowder and diamond crushing materials; for a long time, it has always adhered to this goal and has become the mission of the company.
